PUMP FOR GAS MACHINES OR PLANTS.

SPECIFICATION forming part of Letters Patent No. 452,116, dated May 12, 1891.

Application filed September 17, 1890- Serial No. 365,239. (No model.)

To all whom it may concern:

Be it known that I, ABRAM T. IVELCH, a citizen of the United States, residing at Port Carbon, in the county of Schuylkill and State 5 of Pennsylvania, have invented certain new and useful Improvements in Pumps for Gas Machines or Plants; and I do hereby declare the following to be a full, clear, and exact.de- .scription of the invention, such as will enable 1 others skilled in the art to which it appertains to make and use the same.

My invention relates to an automatic gas machine or plant; and the object of my inventionis to provide an automatic machine I or plant for manufacturing gas from crude petroleum or its products in which water and air are used alternately as a motive power, and bymeans of which the air can be uniformly supplied to the gas-generator and intermixed with the gas simultaneously with the process of manufacturing the same, so that the gas can be consumed directly from said generator without any unsteadiness or fluctuation of the flame. I attain said object by a certain 5 construction, combination,and arrangement of parts fully described in this specification and illustrated in the accompanying drawings, in which Figure 1 is a side View in elevation of my 3 invention complete.

of the opposite side. Fig. 3 is a longitudinal sectional View in elevation. Fig. 4 is a broken sectional view of one of the perforated pipes of the gas-generator 3. Figs 9, 5, and 6 are detail views of parts to be referred to hereinafter. Figs. 7, 8, 9, and 10 are enlarged detail views illustrating the valve-operating mechanism near the top of the inlet waterpipe of the pump 1.

Referring to the drawings, the dotted lines indicate the relative position of parts when the machine is being operated, and similar letters and figures refer to similar parts throughout the respective views. My invention comprises two telescopic cylindrical pumps 1 and 2, the mechanism for operating the same, and the gas generator or tank 3.

The cylindrical pump or blower 1 consists Fig. 2 is a similar View of the outer and larger cylinder A, open at the top, and the inner and smaller cylinder 13, open at the bottom, which closely fits in the cylinder A and works vertically therein. In the bottom of the cylinder A there are four pipes-namely, the inlet water-pipe C, the inlet air-pipe I), the outlet water-pipe E, and the outlet air-pipe F. The air-pipeD extends to near the top of the cylinder A and is provided upon its top with the projecting flanged portions d, with the intervening portions broken away. Said portions are broken away with a view of allowing the air to enter the cylinder when the larger casing or tube 61 is forced'down oversaid air-pipe. Thelower end of the tube d extends slightly under the wa- 65 tor-line w in the compressing-cylinder B of pump 1,thereby preventing the escape of the air after it has entered said cylinder. The inlet water-pipe 0 extends some distance above the top of the pump 1 and contains an enlarged section or collar 0, which may be unscrewed from the lower section of said pipe at c. The extreme top end of the pipe O is provided with a piston 0 which works in the cylindrical tube G. The enlarged section or collar 0 contains a combinationvalve or two stop-cocks H H, which are alternately opened and closed by means of the oscillating or pendulum movement of the right-angled lever or bell-crank I. In other words, upon the sleeves 72 hiof each one of the projecting ends of said stop-cock there are the cross projections h h. The cross projection h has a slot 71 in the lower end of same, into which is adjusted the projecting arm h of the sleeve h of the stop-cock H. (See Figs. 10 and 11.) It will be observed that the other end of the stop-cock H projects sufficiently far to serve as an axle or fulcrum, upon which the wheel I of the right-angled lever or bell-crank I is mounted. This wheel 1' contains upon the outer side a reduced segment I in which works the projecting arm 'i, which is secured in the end of the rod of the stop-cock H. As the 5 wheel I of the right-angled lever I oscillates upon its axle, the projecting arm 'i comes in contact with. the shoulder 'i' of the wheel I and turns the stop-cock H, which has the arm 7L3 adjusted in the slot 702 of the stoncock'Il, by means of which the stop-cocks H ll are opened and closed alternately.

5 Upon the side of the enlarged section there is a pipe J, communicating with the water-pipe O at the junction of the stop-cock 11 and said water-pipe. Said pipe J conveys the water back into the cylinder 3 when [0 the stop-cock II is opened.

It will be observed that the combinationvalve or the stop-cocks l1 and H, are arranged and constructed with a view of accurately regulating the upward-and-downward l5 movement of the inner cylinder B. Each of the sleeves 71 its of said stop-cocks are prov idcd with the set-screw 7L6, whereby the speed of the cylinder 1- in both rising and falling can be nicely regulated in proportion to the opening of the combination-valve or stopcocks ll and 11, which is accomplished by adjusting said sleeves accordingly. This causes less wear and tear and less jump and commotion of the water in the outer cylinder. The cylinder B is provided upon its top with the arch K, which is constructed with the cylindrical tube G upon its top, which has the lower end of same open. In this cylindrical tube the piston 0 works. The downwardly-projecting o arm 1* of the right-angled lever I has upon its lower end the sliding knuckle-joint Z. This knuckle-joint works vertically upon the rod L, which is rigidly secured to the top of the inner cylinder 13. Near the bottom of the 3 5 rod L there is a cross-head Z. Upon the rod L there are also two sliding blocks m, which are moved from point to point upon saidrod, according to the height it is desired to elevate the cylinder B. These blocks are secured at 0 any point upon the rod by means of the thumb-screws m. It is well to note at this point that the right-angled lever I being thus constructed, arranged, and connected, answers the purpose of a balance and check to 5 regulate the cylinder B in its upward-anddownward movement. The size of the weight 1 upon the end of the right-angled lever I is math ematically determined and proportioned according to the relative size of the combina- 5: tion-valve or stopcocks II and II. Hence there is a uniform steady movement.

The cylindrical pump 1 is connected to the cylindrical pump or pressure-regulator 2 by means of the outlet air'pipe F and the outlet water-pipe E. The outlet air-pipe F extends under and through the bottom of the outer cylinder of the pump 2, thence to the top of the cylindrical pump 2, where it is curved over and extends backward tof, and slightly under the water-lineX. This prevents the air from being forced out into the cylindrical pump or water-motor 1. Itis well to mention the fact that the air entering each of the cylindrical pumps or blowers 1 and 2 enters through the air-pipe D to the topof same, thence it passes down to the lower end of the tube (Z and the flanged mouth f of the air-pipe F, both of which are located under the water-line X. In other words, the air in entering is conducted into the water, thence it bubbles up into the cylindrical pumps 1 and 2, respectively. Such being the case, it is impossible for the air to escape through the way by which it enters each of said motors or pumps. There 18 located in the air-pipe F, between these eyhndrical pumps, a stop-cock O, which is opened and closed by means of the L-shaped lever P, which has across-head at p. Said lever is attached to a projecting arm g on the top of the inner cylinder R of the cylindrical pump 2, and is operated by means of the vert1cal movement of the cylinder R. This lever is provided with the sliding blocks 1), which are secured at any point thereon by the setscrews 19 The outlet water-pipe E of the pump 1 extends through the bottom of cylinder A, thence under and up through the bottom of the outer cylinder S of the pump 2, thence through the center of the top of the inner cylinder R, thence some distance above the top of the pump 2. It will be observed that the cylindrical pump 2 is composed of the smaller and inner cylinder R, opened at the lower end, which fits closely and works vertically within the larger and outer cylinder S, which is opened at the top. There is upon the top rim of the cylinder S a sliding post T, which can be made higher or lowerby means of the thumb screw or key 15. In the top of this post there is a slot 25, in which is located and pivoted the lever U, which has upon the end thereof the sliding weight V. Said weight can be secured at any point upon the lever U, between the fulcrum u and the outerend of same. The pivoted lever U is attached to the top of the cylinder R by means of the knuckle-joint \V, and serves, in connection with the weight V, as a check and balance for the inner cylinder R in its vertical movement, making said movement uniform and steady, and free from jerks or jar. There is also in the bottom of the outer cylinder S a pipe X for the escape of waste water. It will be seen that said pipe is elbowshaped and extends upward to the top of the water-line X.

The pump or pressure-regulator 2 is connected with the tank or gasgenerator I} by means of the pipe Y, which communicates with the perforated pipes Z, which extend longitudinally the entire length of said tank. Said perforated pipes Z may, however, be differently arranged, as shown in Figs. 5 and 6that is, they cross each other at right angles and are secured upon a pipe Z of the tank 3, so that they will freely revolve when the air is forced in and much gas is being consumed. This keeps the oil stirred and counteracts the refrigerating process, the. To each of these pipes there is attached the floatvalves .2, which are operated by the floats 2 which are of suffieient size to open and close them according to the height of oil above each of said perforated pipes respectively. These float-valves close as gradually as the oil in the tank is consumed,thereby preventing the escape of air through said perforations when the oil ceases to cover the pipe to which said valve is attached.

There is located at any suitable point upon this tank a suitable main or pipe z, through which the gas is con veyed to the point of storage or consumption. Said tank is provided with an outlet-cock 2 through which the refuse'oil is let off, and also it may have an inlet-pipe, through which water under pressure is admitted, by means of which the tank is thoroughly cleansed.

Y Y represent a pipe that connects the gas-space in the upper part of the tank 3 with the air-pipe y. Said pipe is provided witha regulating-cock 1 by means of which the air is intermixed in any quantity desired with the gas after. the same is manufactured. By the use of the regulating-cock 1 I am able to change the flame instantaneously (while my machine is in operation) from the candleflame to the Bunsen burner blue flame, either of which will be as steady as a coal-oil lamp.

The operation of my machine or plant'is as follows: The tank 3 is first partly filled with crude petroleum or its products until the same covers over several inches the perforated pipes Z. The Water is then admitted into the inlet water-pipe O, which seeks its level and rapidly rises in said pipe until it reaches the topmost cylinder-head of the cylindrical tube G. The pressure of the water between the piston-head c and the cylinderhead G then forces up the cylindrical tube'G until it reaches the point which in turn forces the right-angled lever I to the point 1", thereby closing the stop-cock H and opening 11, respectively, when the water flows down the water-pipe 0 until it reaches the stop-cock H, which is closed. Consequently it passes off through H to the pipe J, thence back into the cylinder 13. As the water thus escapes, the cylinder B falls downward, owing to the displacement of the water in the cylindrical tube G, into the outer cylinder A, compressing the air which has rushed in to fill the vacuum in the cylinder B and forcing the same out through the outlet airpipe F into the inner cylinder R of the motor or pump 2. The water of the motor or pump 1 in like manner escapes through the outlet water-pipe E into the cylinder R, which in like manner is forced to the point i", when the water again exhausts through the pipe X,

which causes the inner cylinder R to fall into its normal position, which compresses the air through the pipe Y, thence into the perforated pipe Z, through which it escapes into the oil and bubbles through the surface of same a gas of the finest quality. Thus it is seen that the water-motor 1 pumps the air automatically into pressure-regulator 2, thence it is likewise forced into the tank or gas-generator 3, and as said air passes through the oil therein it becomes impregnated with the vapors. When the tank is newly charged, all of the fioatsare up, which opens to the full extent the float-valves. The air is therefore first forced through the top perforated pipe until the oil evaporates and lowers. This gradually closes the float-valves on said pipe. The air is then forced through the next lower pipe until the float-valve thereon likewise closes, and so on until all the oil in the tank is used. In other words, the air is forced through crude petroleum or.its products, and is thereby enriched or carhureted sufficiently to be changed into gas.

As I have reduced my invention to practice and tested thoroughly by an operative machine the actual result of same, I deem it useless to enlarge upon its merits. Snffice to 'say it is thoroughly practical and of great Having fully described my invention, what I claim, and desire to secure by Letters Patcut, is
